What this test is

The vitamin B1 test is a laboratory analysis that quantifies thiamine in the blood. Thiamine is a water-soluble vitamin essential for energy metabolism and proper nerve function. The test can help identify low levels that may contribute to certain symptoms.

What it measures

  • Vitamin B1 (thiamine) — reflects the amount of thiamine present in the blood
  • Thiamine diphosphate — sometimes measured as the active form of thiamine in red blood cells
  • Transketolase activity — an enzyme function test that can indirectly indicate thiamine status

What the test involves

A standard blood draw is performed, usually from a vein in the arm, to collect a small sample for analysis. The sample is then processed by the laboratory to measure thiamine concentration.

Why it is often ordered

A clinician may order this test when a person has symptoms suggesting thiamine deficiency, such as confusion, tingling, or muscle weakness. It can also be used to monitor individuals with conditions that affect nutrient absorption or those with increased nutritional needs.

Preparation

Preparation instructions can vary, so it is important to follow the specific directions provided by the collection laboratory. This may include fasting or avoiding certain supplements before the test.

How results are reported

Results are typically reported as a numeric value that is compared to a reference range established by the testing laboratory. Reference ranges can differ between laboratories, so results should always be interpreted in the context of the lab that performed the test.

Before you go

  • Whether fasting is required before the test
  • If any medications or supplements should be avoided
